A search engine was an Internet website used to search for information in the 21st century. A record of one's past searches was called a search history.
Upon entering a term and clicking "search", several links appeared. Searches could be sorted into "All", "Images", "News", "Shopping", "Videos" and "More". Users could "sign in" to the website. (PIC: "Two of One")
DuckDuckGo was one example. (SNW: "Tomorrow and Tomorrow and Tomorrow")
